Abstract
A power transforming apparatus comprises at least two transformers connected parallel to each other between a common power source and a common output, each of said transformers including a primary and a secondary for transforming power from said same power source to said same output. The resistive loss is substantially decreased because the current is split among multiple transformers, and therefore the temperature of the transformer is kept low as less heat is produced from the transformer loss.
